Memdex
Turn every AI conversation into reusable local memory
In plain words
Memdex is a Chrome extension that automatically captures and stores conversations from ChatGPT, Claude, and Gemini in encrypted local storage on the user's laptop. It identifies reusable context from past chats and highlights relevant information in new prompts, allowing users to inject it with a single click. The tool is designed for anyone who wants to retain and reuse information across multiple AI conversations without uploading data to external servers. A free version covers the 10 most recent chats, with a paid plan for unlimited access.

Memdex is a Chrome extension that turns every AI conversation into reusable memory. It auto-captures your chats across ChatGPT, Claude, and Gemini, stores them encrypted on your laptop (IndexedDB, never uploaded), and underlines reusable context in your next prompt like Grammarly underlines typos. One click to inject when you need it just like grammarly. Free for your 10 most recent chats. Pro for unlimited.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
